  • 2020 Toyota Tundra TRD Off-Road – Harrop Supercharger & VF Tuner Tune

    2020 Toyota Tundra TRD Off-Road – Harrop Supercharger & VF Tuner Tune

     
    Clearly, Alex’s 2020 Toyota Tundra TRD Off-Road is no stranger to the trails!  But the added weight of the extra gear, rooftop tent, and larger tires really started to show up in the driving experience, both on and off road.  Alex’s ideal solution was to not only add power, but to do so in a way that wouldn’t affect daily drivability, or reliability on the trails.  And it just so happens that’s exactly what our Stage-2 Harrop Supercharged package delivers for 2007-2021 Tundras!
     
     
     
    This package is configured around the beautifully designed Harrop Engineering TVS2650 supercharger… yep, the same supercharger rotor pack that comes factory equipped on the legendary 755hp 2019 Corvette ZR1 and 760hp 2020+ Ford Mustang Shelby GT500!  Strapping this supercharger to the Tundra’s 5.7L 3UR-FE engine results in not only a significant increase in horsepower, but also a serious increase in low-end torque delivery.  Exactly what a weighed down Tundra needs!
     
     
     
     
     
     
     
    While our Stage-1 package “leaves well enough alone” with just the supercharger, our Stage-2 package takes things up a notch!  Stage-2 additions include ZPE GripTec 80mm supercharger pulley to increase boost pressure, DeatschWerks 650cc fuel injectors to keep up, a custom tune on the dyno via VF Tuner, topped off with optional cooling modifications including VMP Performance supercharger coolant reservoir, CSF Radiators aluminum radiator, with Mishimoto Automotive dual 10.00″ electric fans moving air even at low speed.
     
    Once everything was installed by the shop by Jerzy, the Tundra made her way to the dyno to get a custom tune on the dyno via VF Tuner.  With normal 93 octane in the tank, and the TVS2650 delivering ~9psi, this Tundra’s output increased to 485.80whp & 512.17lbft!  That’s an increase of over 200hp & 200lbft at the wheels over stock!  Pretty incredible results for such a simple combination of parts.

  • Game-Changing Stainless Power Headers For 2016+ Camaro SS & ZL1!

    Game-Changing Stainless Power Headers For 2016+ Camaro SS & ZL1!

    Stainless Power headers for 2016+ Camaro SS & ZL1:  Cheaper doesn’t always mean cheaper…

    The familiar adage of “you get what you pay for” rings true in many cases, but with the release of the all-new Stainless Power headers for the 2016+ Camaro by Stainless Works, a cheaper price no longer means cheaper quality!  Long gone are the days of having to pay $4,000+ for just a header system install and performance tuning – and we are very happy about it!

     

     

    Those of you who have been around the aftermarket automotive performance world will likely recognize the Stainless Works name as they have been a leading manufacturer of high-quality aftermarket header and exhaust systems for many years.  With the new Stainless Power line of header systems you can now enjoy the same great fitment and performance that has been traditionally found in Stainless Works systems at a reduced price!

     

    In this article we will dive deeper into why your 2016+ Chevrolet Camaro SS & ZL1 needs long-tube headers in the first place, and why the Stainless Power headers should be your first choice.  If you’ve already made your decision and are ready to purchase your set of Stainless Power headers today, then read no further and call our team of performance consultants to lock in your install date and get ready to enjoy the newfound power and sound from your Camaro!

     

    What can Headers do for You?

    If you haven’t had the chance to modify your 2016+ Camaro yet you may be wondering what the benefits are from installing long-tube headers.  The primary benefit to most engine modifications is of course an increase in horsepower.  Although modern performance vehicles come equipped with a fairly high-flowing exhaust system there is still performance left on the table, and that’s where long-tube header systems come in.  With a design that incorporates large diameter primaries and high-flow catalytic converters, more air can escape the engine at a much faster rate.  This increase in air flow out of the engine will typically result in a gain of 20-25hp* with proper tuning.

     

     

    The other main benefit of installing long-tube headers is the amazing sound that they generate.  By replacing your vehicle’s factory exhaust manifolds and catalytic converters with the Stainless Power header system you will generate a slightly louder but much more aggressive tone from your exhaust, even with the factory mufflers still in place.  This increase in sound is guaranteed to enhance your driving experience and provide you with a symphony from your exhaust that you are sure to love – even if your neighbors don’t.

     

     

    The Stainless Power Advantage

    Now that we’ve explored the benefits of installing long-tube headers on your Camaro it is time to understand why the Stainless Power systems offer the best value per dollar when compared to other brands.  To start, Stainless Power is produced by the team at Stainless Works who have solidified their place in the market as one of the top-quality manufacturers of aftermarket header and exhaust systems.  Stainless Works systems are manufactured from high-quality 304 stainless steel material, offered in 1-7/8” and 2” primary diameters, provided with high-flow catalytic converters and full 3” exhaust piping up to the factory muffler, and come standard with a limited lifetime warranty.

     

    When comparing the Stainless Works header systems to the all-new Stainless Power offerings we will quickly find that these two products are more similar than they are different.  Stainless Power header systems for the 2016+ Camaro are similarly constructed from 304 stainless steel material, provided with the same high-flow catalytic converters for emissions compliance, and produce nearly identical performance gains and sound once installed.

     

    The differentiating factors that help in providing these benefits at a reduced cost are that the Stainless Power systems are constructed overseas, only offered in a 1-7/8” primary diameter and come with short connection pipes that connect the aftermarket system to the vehicle’s stock exhaust just after the catalytic converters.  After installing several of these systems through our staged performance package offerings we have been able to set our customers up with a system that provides amazing results while also saving them money that they can use towards other modifications. 

     

    With all of these amazing benefits at a competitive price point it is easy to see why the Stainless Power brand is our number one choice in long-tube headers for late model Camaros, Mustangs, Challengers, and more.  Give us a call today and let our team of performance consultants show you how Stainless Power headers can take the performance of your Camaro to the next level!

     

    *Actual performance results will vary based on the final configuration of the vehicle.

    – High Horse Performance, Inc. Crank Pinning Kit
    After Tim finished up the install in the shop, John strapped the Hellcat to the rollers so Vlad could perform a custom calibration. With the additional Stage-2 modifications, the output increased to 804.86whp and 692.42wtq!
     
     
     
     
     
     
     
     
  • What Is Flex Fuel? What It Is And How It Works Explained Simply!

    What Is Flex Fuel? What It Is And How It Works Explained Simply!

    E85 Flex Fuel

    Counter to how it may sound, Flex Fuel is unfortunately not the newest fitness supplement to hit the market.  However, it is a key technology that can aid you and many others in utilizing E85 fuel in your vehicle.  If you’ve recently read our latest E85 fuel overview article then you may be left wondering how exactly you can set your vehicle up to take advantage of all of the great benefits that E85 has to offer.  With Flex Fuel technology this is easier than ever before to take advantage of all the benefits that ethanol-based fuels have to offer.  Join us as we peel back the cob on what Flex Fuel is and how it can help in adding performance to your ride!

     

    What is Flex Fuel?

    Traditionally, if you were looking to operate your vehicle on a fuel other than what it was designed for, such as E85 or racing fuel, you would have to not only install the correct components to support that fuel, but also would have to change your vehicle’s tune to one that is calibrated specifically for that fuel type.  While this may sound simple enough, this process of ensuring that you have fully drained your existing fuel, filled with the new fuel, and then successfully changed your tune can become cumbersome and annoying over time.  With Flex Fuel technology you can now switch from standard gasoline to E85 fuel, or any mix of the two, on the fly without the need for monitoring your ethanol content or having to store and flash multiple tunes.

     

    The way that Flex Fuel can provide this level of simplicity is by using a sensor installed on the vehicle to transmit information back to the engine control unit (ECU) telling it what the ethanol content of the fuel is at that given time.  Once the ECU has determined the ethanol content, it can then make changes to the vehicle’s calibration in real time to compensate for that fuel type.  To actual sensor(s) used to determine ethanol content in a vehicle will vary based on the vehicle type, but there are two primary strategies for gathering this information.

     

    Flex Fuel Sensors

    The first strategy is to use a Flex Fuel sensor that is installed in-line with the vehicle’s fuel system.  The sensor has an inlet and outlet in which fuel from the tank can flow through, and the sensor can detect the ethanol content of that fuel as it passes through.  The sensor then has a direct line of communication to the ECU which can then interpret that signal into ethanol content. 

     

    Because the fuel is flowing directly through the sensor this is by far the most accurate and effective method of interpreting ethanol content.  This is the standard method used in many GM vehicles as well as used in many aftermarket Flex Fuel kits.  Unfortunately, not every vehicle or ECU can support this type of system, so an alternative method called inferred Flex Fuel is required.

     

    Check out of this method of Flex Fuel conversion, as used on A90 Supra, in the video below!

     

     

     

    Inferred Flex Fuel

    For vehicles that are unable to support an external Flex Fuel sensor, the option for inferred Flex Fuel may be available.  The strategy of inferred Flex Fuel relies on oxygen sensors placed in the vehicle’s exhaust system to return information back to the ECU that can then be interpreted into an ethanol content.  While this may sound confusing at first, the method is actually quite simple.  As exhaust gasses pas by the oxygen sensor(s), they will send back a voltage signal to the ECU.  The voltage signal that is sent back will vary based on the air/fuel mixture in the engine at that time.  Because E85 and gasoline have very different stoichiometric values (ideal ratio of air and fuel to support combustion), the voltage readings will be very different when each fuel is applied.  The ECU can then use this information to determine what fuel is in the vehicle at that time and adjust the calibration accordingly.

     

    While this method may sound better due to its lack of additional parts, the fact is that it is not the most accurate way of determining ethanol content and should be implemented with caution.  Inferred Flex Fuel is a reactionary strategy meaning that it takes some time for the engine to run before the sensors will pick up the change in signal and have time to make the necessary calibration changes.  Also, other mechanical variables that cause changes in air/fuel mixture, including something as simple as an exhaust leak, can cause improper oxygen sensor readings that can lead to an improper change in the vehicle’s tune.

     

    Check out our Inferred Flex Fuel calibration for Ford Mustang in the video below!

     

     

     

    Flex Fuel Conclusion

    With the growing popularity of E85 and the huge performance benefits that result from using it, it is easy to see why Flex Fuel technology is extremely beneficial in vehicles that want to utilize this fuel type.  Not only is the process of switching between pump gasoline and E85 made easier than ever, but there is also a large safety benefit available.  Traditionally E85 tunes will run much more aggressive parameters that can be dangerous when lower octane fuel is in place.  In instances where a bad batch of E85 with an unexpectedly low ethanol content may enter your fuel tank, a flex fuel sensor can be an engine-saver by softening the tune based on the actual content realized by the sensor.  For this reason, we believe that Flex Fuel technology is a critical piece for any vehicle using ethanol-based fuels.

  • 1999 Nissan Skyline GT-R V-Spec Makes 550whp On Pump Gas!

    1999 Nissan Skyline GT-R V-Spec Makes 550whp On Pump Gas!

    The R34 Nissan Skyline GT-R: it’s the thing of dreams for the Gran Turismo generation.  But as more have been circulating United States roads in recent years, the resounding sentiment seems to be, “huh, I kinda’ expected more…”  But here’s a quick reminder: these cars weigh in at over 3,400lbs, and typically produce only around 300whp in stock form on our dynos.  Sure, it was competitive for its time, but fast forward to 2022, and there are now several family cars that would pace it door-to-door from a dig.

     

     

    However, this problem has a rather simple solution: more horsepower!  And that’s what Sean brought us his gorgeous QM1 Cloud White 1999 Nissan Skyline GT-R V-Spec to have done.  But before we get into the build details, just look at how magnificently appointed this car is… NISMO Omori Spec LM GT4 wheels, NISMO aero package, even NISMO carbon fiber B-pillar garnishes.  The JDM fanboy in all of us is in love.

     

     

     

     

    And such a spectacularly iconic car needs power to match!  But Sean’s goals for this scope of work wasn’t to break any records, but rather, to “future proof” his setup so he can add more power down the road if (when) he gets the itch.  So, for this round of work, the goal was to make safe pump gas power.  Build details below:

     

    Engine

    • RB26DETT N1 engine block
    • OEM R33 Nissan Skyline GT-R long-snout crankshaft
    • CP Pistons 86mm 2618 forged pistons

    • Custom fabricated aluminum 2.50″ hot-side intercooler piping with 4-ply reinforced silicone couplers
    • Custom fabricated aluminum 3.00″ cold-side intercooler piping with 4-ply reinforced silicone couplers
    • Custom fabricated aluminum 5.00″ air-intake system
    • Custom fabricated 304SS wastegate dump-tubes and down-pipe adapter
     
    Drivetrain
    • NISMO Super Coppermix twin-disc clutch assembly
     
    Engine Management
    • Haltech Platinum Pro stand-alone EMS with CAN WB02
    • Haltech ethanol content sensor (for future Flex Fuel calibration)
    • AEM Performance 3.5bar MAP sensor
    • AEM Performance 3-port electronic boost control solenoid
    • OEM GM intake air temperature sensor
    • Custom calibration by Vlad on 17psi
     
     
    The result is a setup that is overbuilt in the right areas, to not only make the power, but to do so with optimal drivability and long-term reliability.  Prime example, if you’ve never driven a NISMO Super Coppermix twin-disc clutch, then you don’t know how great a twin-disc clutch can drive!  And with that all said, here’s some documentation from this killer build!
